✅ Após resolver os cálculos, concluímos que o valor numérico da diferença entre "f(8)" e "2.f(5)" é:
[tex]\Large\displaystyle\text{$\begin{gathered}\boxed{\boxed{\:\:\:\bf f(8) - 2\cdot f(5) = 2\:\:\:}}\end{gathered}$}[/tex]
Sejam os dados:
[tex]\Large\begin{cases} f(x) = 2x - 6\\f(8) - 2\cdot f(5) = \:?\end{cases}[/tex]
Resolvendo a questão, temos:
[tex]\Large\displaystyle\text{$\begin{gathered} f(8) - 2\cdot f(5) = (2\cdot8 - 6) - 2\cdot(2\cdot5 - 6)\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} = (16 - 6) - 2\cdot(10 - 6)\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} = 10 - 2\cdot4\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} = 10 - 8\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} = 2\end{gathered}$}[/tex]
✅ Portanto, o resultado é:
[tex]\Large\displaystyle\text{$\begin{gathered} f(8) - 2\cdot f(5) = 2\end{gathered}$}[/tex]
[tex]\LARGE\displaystyle\text{$\begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered}$}[/tex]
